The written consists of 2 parts A and B. Section A is 20 questions that IMO are about 25% harder than those on the 2381. each question carries about 3 marks each.
Section B consists of about 6 questions that are more difficult, more sums based. e.g they will give you a sinario say a house extension and give you some of the information i.e. R1+ R2 and PFC, they then ask you to calculate the rest and fill out an EIC. Stuff like that,
Is is Regs based, mainly in section A I would say
Think you have to get at least 60% on each paper with a total of over 80% so even if you get 100% on A you still need over 60% on B (edit does that add up I dont know tis what we were told anyhow)
The practical consists of 3 easy tests. Faults board, Insulation resistance and Zs measurement
The big test is a full PIR on a 3ph board with single ph sub main. Highly pressured with a bonce looking over you shoulder all the time, easy to make a mistake and they are very big on safety i.e. safe isolation etc.
